TW410199B - Treatment of materials to improve handling of viscoelastic fluids and its products - Google Patents

Abstract

Disclosed is an improved structure that includes a nonwoven web including a viscoelastant treatment. The treated web, when contacted by a viscoelastic fluid such as menses alters the viscoelastic properties of the fluid and enhances its wicking and distribution throughout the absorbent structure. A desirable viscoelastant is a alkyl polyglycoside, particularly those having 8 to 10 carbon atoms in the alkyl chain. When applied so as to provide an amount of about 0.1% to about 5% solids add-on based on the weight of the dry nonwoven web, rapid fluid wicking and distribution may be obtained. Other viscoelastants are disclosed. Advantageously the treatment may be applied as a high solids composition using conventional application means such as spray coaters and the like or as an internal additive. The absorbent structure finds particular utility as a distribution layer component of a sanitary napkin for absorbing menses as well as other blood handling products.

A7 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 410199 V. Description of Invention (1) The priority of this application is from the US Provisional Application No. 60/02 5,609, filed on September 4, 1996. . Invention backings There are many @applications about materials that can be quickly absorbed, and / or transport fluids such as body waste and the like. Examples include disposable personal care products such as disposable diapers and children's training pants, and women's hygiene. Such as tampons and tampons, as well as incontinence care products such as general and clothing. Other industrial products such as rags, oil absorbing products, and moist products with such items fitted for health care items such as bandages. Because these fluids have different characteristics, it is desirable to make a material discardable after use: It is very difficult to have all these requirements in an economical consideration, which is also a common requirement for many such applications. In particular, fluids like menstruation, which have viscous and elastic properties, will pose great challenges to traditional absorption and dispersal levels. The viscous and / or elastic components of such fluids will increase special requirements for absorption and / or dispersion phenomena. These requirements are often matched by the best performance of the other components of the fluid, with less stickiness and flexibility being the compromise needed to improve overall performance. For example, there are pores and capillary sizes' on an ideal material for absorbing and dispersing smaller dry elastic components and are different from those that have the best effect on the more viscous elastic components. After many efforts, a material structure has been developed into non-woven fabrics, foam plastics, films, and the like to meet all the requirements, but it has not been completely successful. Another-the processing method is to adjust the viscoelastic properties of the U itself.

Description of the invention (2 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs, which regulates the viscous and elastic fluids. Most of the difficulties ^ are difficult to accumulate, including agents that affect intermolecular binding, and entanglement of huge molecules. Non-woven fabrics and their manufacturing palms have become the mainstay of DaFu's development because they can be used in a wide variety of materials in many applications. ^ For example, light-weight and open-structure non-woven fabrics Used in personal care product items, such as disposable diapers and lining fabrics that provide wide contact with dry leather; however, for the rapid transfer of fluids to more absorbent materials, it may be different for non-wovens. The composition and / or structure varies. For many applications ^, the ability to wick or transport viscous fluids such as menses, etc., is provided by dispersing this fluid to provide The maximum utilization of the absorption properties of the products, or the materials placed below, which affects the efficiency performance of these products is very important. In other applications, performance-measured nonwovens can be designed with pores, which makes them suitable for use in Filtering, absorbent and barrier applications, such as packaging for sterilizing articles, medical rags or protective clothing, veterinary or industrial applications, etc. It is a performance measurement non-woven Have been developed for recreational, agricultural, and architectural applications. The only non-woven fabrics with virtually unlimited shapes and their uses are known to those skilled in this technology, and they also admit that they have been identified There are new nonwovens and their applications. Different methods and devices have been developed to give nonwovens the desired structure and composition suitable for use in this application. Typical such processes include spunbonding, melting Spray method, carding method and other square enamels will be described in more detail below.

Description of the invention (3 is not always effective — A non-woven fabric with all desirable properties, and it must often be treated with this non-woven fabric in order to enhance or change its characteristics, just to name a few, such as-the wetness, absorption or dispersion characteristics of multiple fluids' -Or more material repellency, material properties, conductivity and softness. Conventional processing involves steps such as impregnating a non-woven container, coating or spraying with a processing ingredient, and printing and dyeing the non-woven with a processing ingredient. For cost and other reasons, it is expected that only a minimal amount of processing composition will be used to achieve an acceptable level of uniformity and produce the desired effect. For example, it is known that the heat added by the additional drying step to remove and process the radon generated by the composition application will adversely affect the% physical properties of this fabric, and at the same time increase the flower # of the processing process. At this point, it is expected to provide a non-woven fabric with a modified treatment method, and / or composition, which will effectively and practically apply the desired treatment 'without adversely affecting the desired non-woven characteristics. While achieving the desired result. More specifically, it is expected to provide a treated non-woven fabric suitable for viscous fluids, and to have properties that can change properties such as the viscosity and / or elasticity of an invading viscous fluid, so as to control the movement of the fluid, such as Absorption, dispersion, and adsorption in personal care products such as sanitary napkins.

Description of the Invention (4) Sanitary napkins and tampons, baby and childcare articles such as diapers and child training pants, end bands, incontinence products, and wipes And absorb oil products. According to the present invention, the structure comprises a synthetic, and usually normally hydrophobic, enzyme-containing substrate containing a viscoelastic agent for contact with this viscoelastic fluid. Advantageously, the enzymatic substrate is non-woven and may be, for example, a spunbond, meltblown, coform or bonded carded fabric. Additives that may be used include foams and films formed from fibrils, perforated, or otherwise treated to give fiber-like properties, and laminates and / or nonwovens of these materials. Depending on the particular application, this structure can be used as an integral side contact pad, or as a dispersing layer, an absorbent layer, or a plurality of these layers interposed between a pad and an absorbent layer. When in contact, the structure of the present invention can change the viscoelastic material of the fluid, so as to improve the absorption, scatter and absorption characteristics of the fluid. It is expected that 'this adhesive is not harmful when used, and it is not harmful to the environment when disposed. Useful examples include alkyl polyglycosides having 8 to 10 carbon atoms present in the alkyl chain. These alkyl polysaccharides change the viscoelastic properties of viscoelastic fluids and increase the wettability of synthetic surfaces. Examples of other viscoelastic agents include tallow extract surfactants [Survanta, Survanta Ross Laboratories), barriers to treat symptoms of acute dyspnea and cystic fibrous lesions, and Enzymes such as papaya enzymes or pepsin. Certain dextrins and glucose are also used as viscoelastic agents. Dextran (macromolecule) is a glucose polymer with a chain structure. Usually, dextran produced by sucrose through the action of bacteria has a molecular weight as high as 200,000.

Another unit often used to indicate fiber diameter is denier, which is defined as the number of grams per 900 meters of fiber, and the fiber diameter can be squared in micrometers, multiplied by the density in grams per cc. Then multiply by 0.00707 to get 6-a lower Daniel represents a thinner fiber, and a higher Daniel represents-a thicker or heavier fiber. For example, 'a 15 micron diameter polypropylene fiber' can be converted to a Daniel number by squared the result, then multiplied by 0.89 g / cc, and then multiplied by 0.00707. Therefore, a 15 micron poly Acrylic fibers have a denier ratio of approximately 1.42 (152 X 0.89 X 0.00707 = 0.41 5). The unit of measurement outside the United States is usually "quote" (tex), which is defined as grams per kilometer of fiber. Tex can be calculated by Daniel / 9. The term "spunbond fiber" as used herein means that by extruding a melt-blown thermoplastic material such as a long fiber from a spinneret having a plurality of small and usually crimped capillaries, the fiber is then extruded.

Description of the invention (14) The word " blend " will be defined below. The bicomponent fiber does not have a variety of polymer compositions arranged in a clear area relatively fixed across the cross-sectional area of the fiber, and the various polymers do not usually show along the entire length of the fiber Instead, 'fibers' are replaced by fibrils or fibrils that usually form any beginning and end. Bicomponent fibers are also sometimes referred to as multicomponent fibers. For this, a general type of fiber is discussed in U.S. Patent No. 5,108,827, filed by Gessner. Two-component and two-component fibers are also explored in the bibliography of Johan A Manson and Leslie Η Sperling, polymerized makeup and nude compounds, published by Plenum in 1976, p | enum Publishing Co., Ltd., New York, IBSN 0-306-30831-2, pages 273 to 277. As used herein, the term "selective compound" used in polymers refers to a mixture of two or more polymers, while "doped" refers to a secondary blend 'its Composition is not miscible with each other but still compatible β " easy miscibility " and immiscibility ", with respect to the free energy of mixing, are each defined as a blend with negative and positive 値. Furthermore, " compatibility " is defined as a process that adjusts the interfacial characteristics of an immiscible polymer blend to make a replacement. As used herein, air bonding or "TAB" means a process of bonding a non-woven fabric. Take a pair of constituent fiber fabrics as an example. The air is sufficiently heated to melt one of the fabric fibers. Polymer to force the fabric fibers to form a fabric. The speed of air is usually between 100 and 500 feet per minute, and the residence time can be as long as 6 seconds. The melting and re-solidification of the complex will provide the required bond.

If used, the total amount of lye will usually be less than about 5 weight percent of this layer, and the total amount of other additives will be less than about 25 weight percent. The fibers of the fabrics of the present invention can be produced by meltblown or spinning processes including those known in the art to produce bicomponent, bicomponent, or polymer blend fibers. These processes typically use an extruder to provide a fibrillated molten thermoplastic polymer, which is produced through a spinneret, which can be staple fiber length or longer. The fiber is then drawn, usually pneumatic, and deposited on a moving porous plastic or belt to form the nonwoven. The fibers produced in the spunbond and meltblown processes are microfibers, as defined above. The manufacture of meltblown weaves is discussed briefly above and in the references. As mentioned, the non-woven fabric may also be a bonded carded fabric. Bonded carded fabrics are made from staple fibers and are usually purchased as a trim. This whole bundle of staple fibers is placed on a cotton bomber to separate the fibers. The fibers are then sent through a combing or carding unit, further broken and separated, and the staple fibers are aligned in the mechanical direction to form a fibrous non-woven fabric, which is generally mechanically oriented. Once this fabric is formed, it is then bonded by one or more individual bonding methods known in the art. One of the bonding methods is powder desiccant bonding. One of the powder bonding agents is dispersed throughout the fabric, and then the fabric and the bonding agent are usually activated by hot air. Β Another suitable bonding The method is a model bonding method, in which heated calender rolls or ultrasonic bonding equipment are used to bond the fibers together. Although it is expected that the fabric can be bonded across its entire surface, but It is usually sticky in areas

In an embodiment-a typical multilayer laminate, some of the layers are spun hybrid and some layers are meltblown, such as a spunbond / meltblown / spunbond (SMS) laminate, which is disclosed In U.S. Patent No. 4,041,03 applied by Brock, et al., U.S. Patent No. 5,169,706, applied by Collier, et al., And U.S. Patent No. 4,374,888, applied by Bornslaeger. This laminate can be deposited by sequentially depositing a spunbond fabric layer on a moving forming belt, then a meltblown fabric layer, and finally another spunbond layer, followed by a method described below This laminate is bonded together. Another option is that 'this fabric layer can be individually rolled up on the rollers, and bonded together in separate steps. Such fabrics usually have a basis weight from about to 12 osy (6 to 400 gsm) 'or more specifically from about 75 to about 30 sy. The treatment according to the present invention may be performed by an in-line manufacturing process of a non-woven fabric, or by using an off-machine pre-manufactured enzymatic substrate or a non-woven fabric. Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives Spunbond nonwovens are usually bonded in some way to provide their full structural integrity and withstand further rigorous processing to produce the final product. Bonding can be done in several different ways, such as hydroentangling, knitting, ultrasonic bonding, adhesive bonding, needled bonding, air bonding, and thermal bonding .

This type of processing is described in U.S. Serial No. 08 / 665,172, jointly assigned by Yahiaoui, Ning, Bolhri, McDowall, Potts, and Van Hout on June 14, 1996, which is hereby incorporated by reference in its entirety. for reference. In the site of the reactive species, the affinity of the hydrophilic polymeric material for the porous hydrophobic polymerized enzyme substrate will be enhanced. By way of example, the site of the reactive species may be a corona field. As shown in another example, the site of this reactive species may be a plasma field. Without wishing to be bound by theory, it is believed that exposing the porous hydrophobic polymerized substrate to a reactive species site will cause the surface of the substrate to be denatured, and therefore temporarily increase the substrate. Surface energy. This will allow the treatment solution to enter the porous enzyme substrate; that is, 'the porous enzyme substrate will be saturated with the treatment solution. Although exposing this porous substrate to the site of a reactive species is a promising method for temporarily increasing the surface energy of the substrate, other treatment processes can also be applied. For example, the porous substrate can be treated with ozone or passed through an oxidizing solution, such as an aqueous sample medium containing chromium trioxide and sulfuric acid. However, other processes need to be handled carefully to avoid Or minimize the degradation of this porous substrate. The strength of this reactive species site can be varied using control methods that span at least one area of the fibrous fabric. When the porous enzyme substrate is coated with a hydrophilic polymeric material, the extent and extent of the hydrophilicity of this coating will be directly proportional to the strength of the site. At this point, the hydrophilicity of the coating of the polymeric material will be controlled by at least one area spanning the fibrous fabric &

Other viscoelastic agents are now obvious to those skilled in the jaw field. For example, they include but are not limited to tallow extraction surfactants (Survanta® , Pugui Lab), and proteolytic enzymes such as wood yeast and gastrin, as well as specific pastes and glucose.
